Answers
1
Some elephants have tusks while others do not. Which tenet does this represent?
competition/struggle for existence
variation
heredity
differential reproductive success
2
What is indicated by the splitting of a tree branch on the tree of life?
a new breed
a common ancestor
a mutation
a new trait
3
Which organelle did organisms have first - chloroplasts or mitochondria?
plants don't contain mitochondria
chloroplasts
they appeared at the same time
mitochondria
4
Mutations always cause which of the following?
changes in enzymes
changes in the sequence of carbohydrates
changes in the sequence of DNA
changes in the sequence of amino acids
5
How can the tree explain “The Theory of Endosymbiosis?"
By the length of a branch
By the splitting of a branch
By the changes in the color of branches
By the changes in the color of the branches and the leaves.
6
How does a mutation make it possible for evolution to occur?
the mutation is silent
the mutation does not change the amino acid sequence
the mutation is beneficial for the organism
the mutation has a negative effect on the organism
7
What is the common ancestor of all living organisms?
All organisms have DNA.
All organisms evolved from eukaryotic cells.
All organisms evolved from fish.
All organisms evolved from prokaryotic cells.
8
Where did Darwin develop his theory of evolution by natural selection?
Galapagos islands
Australia
Madagascar
South America
9
A tuskless elephant has a tuskless baby. Pick the tenet this represents.
variation
differential reproductive success
competition
heredity
10
What type of organism is a whale’s closest living relative?
horses
dogs
humans
cows
11
How do horses show us that evolution occurred?
Horses provide molecular evidence of evolution.
There are many species of horses living today.
Horses provide a strong fossil record.
Horses can mate with donkeys.
12
If a donkey and a horse make a mule, why aren’t they considered the same species.
Mules can only mate with a horse or a donkey.
They look so different
Mules are really just ponies.
Mules are sterile.
13
The proportion of tuskless elephants has increased due to ivory trade. Which tenet is this?
heredity
differential survival and reproduction
competition/struggle for existence
variation
14
Which most accurately describes speciation.
two different species are able to produce offspring
a species is separated and two populations diverge over time
breeding many types of dogs such a a pug, beagle, and boxer
a species is separated and can no longer mate if reunited.
15
Elephants are hunted and killed for their ivory. Which tenet is this?
differential survival and reproduction
variation
competition/struggle for existence
heredity
16
Why did Darwin take so long to publish “On the Origin of Species?”
Fear of being shunned due to religion.
His wife told him to wait.
Other scientists were confirming his findings.
Wallace published his book first.
17
Based on the hemoglobin sequences which two species are the most closely related?
Orangutan and Gorilla
Chimpanzee and Gorilla
Gorilla and lemur
Chimpanzee and orangutan
18
What types of organisms do not contain mitochondria?
plants
animals
bacteria
fungi
19
Which of the following finches eat insects?
Warbler finch
sharp-beaked ground finch
vegetarian tree finch
cactus ground finch
20
Which of the following best defines evolution?
changes in a allele frequencies in a population over time
emergence of new species over time
changes in the appearance of a population over time
changes in the alleles in an individual over time
21
Which is not a line of evidence that evolution has occurred / is occurring?
molecular biology
embryology
microbiology
biogeography
22
Which of the following best defines a theory?
description of an observed phenomenon
fact based explanation that has been repeatedly confirmed
a hunch or speculation
a hypothesis that you test through study and experimentation
23
What line of evidence includes embryology?
molecular biology
comparative anatomy
analogous biology
biogeography
24
When mutations occur, they are usually
beneficial
noisy
silent
detrimental
25
How could you use this tree to explain that we did NOT evolve from monkeys?
Humans did evolve from monkeys.
Humans evolved from chimpanzees.
The tree shows that monkeys evolved from humans.
The tree shows humans and monkeys have a common ancestor.
26
During the drought on Daphne major all of the small seeds were destroyed.
This caused finches with small beaks to leave.
Large beaked finches cracked seeds for small beaked finches.
This caused finches with small beaks to evolve.
Small beaked finches weren't able to survive to reproduce.
